Mr. PizzaHacker, Jeff Krupman, is something of a familiar face here on Slice: Adam Kuban interviewed him back in 2010 about his mobile Frankenweber operation, and David Kover reviewed that popup circa 2011. For a low-key weeknight, the newly opened PizzaHacker brick and mortar on Mission Street has swiftly become my go-to.

Though pop-up food vendors have become the norm around San Francisco, watching The PizzaHacker (aka Jeff Krupman) cook up street-corner pizzas in the wood-fired oven he fashioned from a Weber grill is something else entirely. On a typical PizzaHacker outing, Krupman has the oven burning between 800 and 900 degrees and turns out pies in under two minutes.
